3 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4 * src/z80/main.c (_keywords[]),
5 * src/SDCCglobal.h (struct options),
7 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
8 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
9 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
10 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
11 always available in leading double underscore form. The C99 support is
12 mostly missing, but it's a start.
13 * support/regression/tests/bug-227710.c: fixed nonconforming use of
14 reserved identifier "__data".
16 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

58 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
59 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
60 immedDom() returning wrong block; probably fixes bug #1160833)
62 2005-03-20 Borut Razem <borut.razem AT siol.net>
64 * support/scripts/inc2h.pl: WIN32 port
66 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

87 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
89 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
90 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
92 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
94 * device/lib/printf_large.c: removed inline assembly for portability and
95 readability. Use printf_fast if speed or size are more important.
96 * src/pic16/gen.c: removed conditions around use of DEBUGpc
97 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
99 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
101 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
102 prevent compiler warning
104 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
106 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
107 moved to level 0 and declared as static. Also they are explicit
108 placed in access bank. This was necessery because some times they
109 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
110 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
111 optimizations. Currently only compare to unsigned char is implemented,
112 * src/pic16/gen.c: added fReturnIdx array,
113 * (struct resolvedIfx) is moved to gen.h and made public,
114 * (struct _G): added sregsAlloc and sregsAllocSet fields,
115 * (aopForSym): added an optimization to directly store in stack of
116 the operand of a SEND iCode,
117 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
118 but as registers instead (AOP_REG) using the fReturnIdx array,
119 * (pic16_freeAsmop): remove the freed register from the
121 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
123 * (pic16_popGetTempRegCond): changed function prototype, now
124 function takes also a bitVector argument v which holds the current
125 set of registers that are allocated for stack access by aopForSym,
126 registers allocated in aopForSym for accessing stack symbols are not
127 any more part of the functions usedRegs field,
128 * (genCall): some times aopOp is called for a stack variable to be
129 send, aopForSym might perform the push, if this is true make sure
130 that genCall doesn't push the variable twice by testing _G.resDirect,
131 * (genFunction): changed testing for unspecified interrupt number
132 from 256 to INTNO_UNSPEC,
133 * modified selection scheme of frame pointer generation. Previously
134 if function did use local registers a frame pointer was generated,
135 now a frame pointer is generated only if function has arguments
136 (that need PLUSW2 register access), or has stack arguments, or the
137 compiler is not instructed to omit the frame pointer,
138 * (genEndFunction): before restoring local registers that were saved
139 in the function preamble, also restore the registers that *might*
140 have been allocated for stack access,
141 * (genRet): removed some old comments,
142 * (genCmp, the active (RN's) version): added a call to the
143 pic16_genCmp_special function to perform the compare with a more
144 robust and optimized way,
145 * (genInline): a feature has been added in inline code generation,
146 which allows a wildcard variable substitution when writing inline
147 assembly. Code is incomplete and experimental therefore undocumented,
148 * (genCast): changed order of aopOp for result and right to allow
149 aopForSym to directly load the result if possible,
150 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
151 perform an optimized compare on some selected special occasions,
152 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
153 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
154 generate an IVT any more,
155 * src/pic16/main.c (pic16_optionsTable): added command line option
157 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
158 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
160 * src/pic16/NOTES: Raphael Neider added in list of active developers
161 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
162 jumptable_end to prevent bug #,
163 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
164 inCond and outCond fields,
165 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
166 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
167 turn off register spilling,
168 * (packRegsForOneUse): synced with other ports' versions although it
169 is not used currently,
170 * (pic16_packRegisters): added an optimization while reading
171 structure bitfields, some registers may be saved (malloc code is
172 decreased by 80 bytes)
174 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
176 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
177 left is a bitfield, if yes, then don't optimize assignment. Perhaps
178 this can be optimized more?
180 2005-03-10 Raphael Neider <rneider AT web.de>
182 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
183 genNearPointerGet): (hopefully) fixed access to bitfields via
184 pointers (p->bitN = x; and x = p->bitN; failed)
186 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
188 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

229 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
230 to keep the correct label reference count when adding/removing references
231 to labels. A peephole file using this is appended to patch #1144962.

469 operands (genAddLit expects the iCode's operands to swapped as
470 well), fixed leftover bytes (crashed for short left operands)

876 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
878 * (genCast): began a fix to optimize the casting of a bit to another

3902 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3904 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3905 loaded with the linker search paths (-L arguments) and the libraries
3906 to be linked with the current source (-l arguments). Changes
3907 currently will affect only the pic16 port.
3908 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3909 include path the port specific paths and port specific libraries,
3910 * gplink command now contains the $3 argument,
3911 * src/pic16/device.h,
3912 * src/pic16/device.c,: structure PIC_device is made public and
3913 renamed to PIC16_device, the same for variable Pics which is renamed

3928 Documenting changes from previous commits.
3929 * configure.in (version 1.56),
3930 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3931 when generating output files to configure the pic16 library,
3932 but now I've commented it out, since gputils aren't installed in the
3933 SF compile farm, so library won't compile
3935 * device/lib/Makefile.in (version 1.56): initially I've added in
3936 target 'all' the prerequestive 'model-pic16' so it compiled the
3937 pic16 library, but now I've commented it out for the same reasons
3939 * added targets 'model-pic16' and 'objects-pic16' to compile the
3941 * added target 'port-specific-objects-pic16' to handle the
3942 generated libraries and copy them into the build/ directory
3943 * added target 'clean-intermediate-pic16' to clean intermediate
3944 files into pic16 directory
3945 * in target 'installdirs' added line to create directory pic16 in
3946 the installation path

3949 added lines to copy all header files to installation path,
3950 * in target 'installdirs' added line create directory for pic16
3951 headers in the installation path

3967 option so that it actually works. Made it specific to the z80, since
3968 the gbz80 doesn't have these kinds of I/O ports.
3970 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3972 * device/include/z180.h,

3996 via literal number. The symbol is placed in the corresponding
3997 position of the data ram
3998 * (pic16_dump_section): relocatable and absolute uninitialized
3999 data are now emitted in sorted order to reduce section naming,
4000 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4001 weren't marked as being in the access bank,
4003 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4005 Added portion of GNU PIC Library under the directory
4006 device/include/pic16 and device/lib/pic16. These files
4007 contain the declarations of SFRs for the PIC18Fxx2 devices.
4008 The directory is initialized via configure from toplevel.

4039 to better keep the right margin. Changed some notes about
4040 maintainance of the ports in section 3.2.1 - is it OK like this?
4042 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4044 SDCC source changes:
4045 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4051 processor registers declared internally by the port are emitted in
4052 the translation as equates,
4053 * src/pic16/gen.c: inline code is passed unprocessed to the

4194 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4196 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4197 (default behaviour).
4199 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4201 A python script to validate compiler diagnostic messages. It can be
4202 used to verify that sdcc complains about bad c source code and
4203 gives a good location of the error.
4204 * support/valdiag/Makefile,
4205 * support/valdiag/valdiag.py,
4206 * support/valdiag/tests/*

4221 * src/common.h: added ifndef/define/endif macros
4222 around the header file.
4223 Bug reported from Jesus Calvino-Fraga
4225 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4227 * sdcc.spec: updated
4228 * device/include/Makefile.in: don't install CVS directories
4229 * device/lib/Makefile.in: added removal of CVS directories after install
4230 * doc/Makefile: fixed install, added local_icons
4231 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4232 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4233 * src/ds390/gen.c (genRightShift): fixed bug #870788
4234 * src/SDCCast.c (decorateType): fixed bug #870781
4236 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4238 PIC16 port related changes:
4239 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4240 added variable stackPos,
4242 * gen.c: genCall, assignResultValue: added support for
4243 pushing/retrieving function parameters to/from stack,
4244 genFunction,genEndFunction: setup stack frame for the
4246 genAddrOf: will be changed according to bug 863624
4248 * added files genutils.c and genutils.h which contain gen*
4249 debugged and optimised functions extracted from gen.c
4251 * glue.c: added variable 'externs' which holds extern symbols,
4252 pic16emitRegularMap: is modified to properly handle relocatable
4253 symbols under the new scheme,
4254 pic16createInterruptVect: is modified
4255 pic16printPublics: is modified to emit 'global' assembler directives,
4256 added pic16_printExterns to print extern symbols,
4257 pic16glue: initializes stack/frame pointer in the beginning of
4258 the assembly output. Temporary hack, will be corrected later,
4259 because gplink yet does not support stack and SDCC does not
4260 yet support a type of crt0.o object to create the final binary.
4262 * Removed many lines that contain 8051 legacy code.
4263 * The code is finally placed under a 'code' directive.
4264 * Added port specific options.
4266 * _process_pragma: simplified since now we do not need *special*
4267 include file to define SFR registers. But a separate header
4268 will be needed. This will be developed later.
4269 * _pic16_parseOptions: added, parses port specific options:
4270 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4271 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4272 --preplace-udata-with=
4274 * _pic16_setDefaultOptions: modified to initialize section names,
4275 but hack is temporarly out of order since it needs improvement.
4276 * _pic16_genAssemblerPreamble: configuration words are emitted by
4277 their address instead of their name. This part is incomplete and
4278 supports only the 18Fxx2 devices. Other devices will emit an error
4279 during assembly since they do not contain the same set of config
4281 * _pic16_genIVT: is modified,
4283 * pcode.c: added definitions for some hardware registers that are needed
4285 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4286 All PCI entries are updated. Now LFSR is supported.
4287 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4288 * added pic16_newpCodeOpLit2 to support instructions with
4289 two literal arguments
4290 * pic16_pCode2str: corrected code that emits assembler instructions
4291 with two literal operands and those that have an access bit modifier
4292 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4293 this fixes a bug which caused some labels to be lost, when an
4294 assembler directive was added, i.e. banksel,
4295 * pic16_FixRegisterBanking: improved logic that causes the insertion
4297 * InlineFunction: functions that are called once, are not any more
4298 inlined. This can be a port option in the future,
4300 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4302 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4303 hold the corresponding uninitialized symbols,
4304 * pic16_allocProcessorRegister: registers have explicit marked the
4306 * pic16_allocInternalRegister: registers are explicit marked as
4308 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4309 processing list, so bit registers were lost,
4312 * ralloc.h: added field 'accessBank' and original symbol operand
4313 in register definition,
4314 * removed the field isMapped from register definition,
4316 ** Several functions have been removed from various sources:
4317 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4318 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4319 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4320 pic16_assignRelocatableRegisters
4322 ** others have been introduced:
4323 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4324 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4326 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4328 * support/scripts/inc2h.pl: changed definition of BIT_AT
4329 to emit 'sbit at' instead of 'bit at'. This was a request.
4331 PIC16 port related preliminary changes:
4332 * gen.c: prefixed function popRegFromString with
4333 pic16_ and all references to it corrected
4334 * pcode.c: all pic16_pc_* hardware registers prefixed
4335 with underscore (_),
4336 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4337 * ralloc.c: newReg(): when register is REG_SFR then
4338 set address to rIdx,
4339 pic16_allocProcessorRegister(): marks register wasUsed=0
4340 pic16_writeUsedRegs(): added a call to assign processor
4341 registers via pic16_assignFixedRegisters
4343 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4345 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4346 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4347 variables in unused register banks. Also the SSEG is placed
4348 wherever there is enough space for it, and IDATA can be anywhere
4349 in internal RAM. For now compile using -Wl-Y[stack_size].
4350 The mem file is different for this option as well, since it
4351 makes no sense of talking about DSEG lenght.
4353 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4355 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4356 in certain cases, e.g. when ROM assignment, patch provided
4357 from Albert den Haan.
4359 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4500 xdata and data memory on startup. Set the environment variable
4501 SDCC_NOGENRAMCLEAR to disable this.
4502 * src/mcs51/peephole.def,
4503 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4504 (allows non-interrupt and interrupt code to safely compete for a resource

4515 multiply defined with mismatching "at" address.
4517 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4519 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
4520 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

5245 support for standard C idiom of memory mapped variables; for
5246 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5247 to xdata int at 0x1234 tempvar = 1.
5248 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5249 provided by Akiya ISHIDA

5265 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5267 Fixed bug #621531 (const & volatile confusion in the type chain).
5268 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5348 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5349 iCode properly now. Use getSize instead of nRegs since a & b
5350 aren't part of the nRegs tally.
5352 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5354 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

5360 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5361 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5362 fetching of the pointer
5363 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5364 copied from genNearPointerSet()
5365 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5366 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5367 If they pop r0/r1 they must be called in the opposite order than aopOp().
5368 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5369 (resp. --stack-auto), prepared for --xstack

5378 these ports have their own __sdcc_external_start()
5380 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5382 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5383 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5384 type for bits was changed. It resulted in bit variables becoming
5385 global, which is not permitted in PIC 14 assembly output.
5387 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5389 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5400 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5402 A few small changes that speed up the peephole optimizer.
5406 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5408 Try to make the peephole optimizer smarter by maintaining
5409 an association between the assembly source code and the
5410 iCodes that originated them. Put this information to use
5411 with a new peephole rule condition "notVolatile" so that
5412 the rules can be aggressive yet still safe.
5417 * src/mcs51/peeph.def
5419 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5423 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5424 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5425 if the left or right operand symbols have the accuse flag set.
5427 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5429 Changed the type of the result of the ! (NOT) operator to char;
5430 previously it returned the same type as the source. This allows
5431 us to eliminate all the genFloatNot functions (all of its target
5432 implementations were very buggy) since !float can use the same
5435 * src/SDCCicode.c (ast2iCode): ! returns char

5437 * src/ds390/gen.c (genNot, genNotFloat),
5438 * src/z80/gen.c (genNot, genNotFloat),
5439 * src/pic/gen.c (genNot, genNotFloat),

5442 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5444 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5445 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5446 during interrupts. Ensure WSAVE is located at a shared bank address.
5447 2. Fixed page selection in some places
5448 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5449 the registers name strings.
5450 4. Fixed "signed / unsigned compare" compiler warnings.
5451 5. The PIC port manages its own allocation of the general purpose
5452 registers, but makes no attempt to reuse them. As a result when
5453 compiling it soon runs out of general purpose registers. Some
5454 additional code was added to the files pcode.c and device.c to walk
5455 through the function call tree and rename the registers so that they
5465 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5466 genPlus() & genMinus() when the result is the same as left or right
5468 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5472 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5474 Made bitfield a distinct type from bit so that bitfields
5475 convert as per ANSI C and bits retain their traditional
5476 boolean style behaviour. Implemented bitfield support in
5484 * src/ds390/gen.c: bit v bitfield split
5485 * src/z80/gen.c: New support for bitfields
5486 * support/regression/tests/bitfields.c: reenabled z80,
5489 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5491 Rules 246.x, 247.x relate to bitfields, the others speed up
5492 access to xdata mapped I/O devices.
5494 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5496 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5498 Cleaned up genPackBits and genUnpackBits and added two helper
5499 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5500 for literal assignments in genPackBits (thanks to Frieder for
5506 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5508 Fixed bug #748310 (pointer to function type mishandled when the
5509 function name is omitted). Also fixed a SIGSEGV when a function
5510 attribute (reentrant, etc) is used on a non-function or on a
5511 function but misplaced before the parameter list.
5513 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5515 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5516 * support/Util/SDCCerr.h,
5517 * support/Util/SDCCerr.c: Added func attr misuse error msg
5519 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5521 Fixed bug #787649 by anonymous
5522 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
5523 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
5525 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5538 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5540 Made the constant following the "interrupt" keyword optional. If
5541 omitted, the function will not automatically be given an entry
5542 in the interrupt vector table (similar to #pragma NOIV, but
5543 less syntacticly kludgy). The interrupt number is also now
5544 range checked. Also fixed a bug in the high order bit example

6071 added --disable-pic16-port
6072 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6073 * src/SDCCmain.c: linkOptions is changed to set *,
6074 added if/endif conditional macros to remove options help
6075 messages from optionsTable when a port is not configured, added
6076 support for the PIc16 port in the ports table, when executing
6077 the compiler with no port specified on command line, a default
6078 port is selected with the new macro DEFAULT_PORT which is
6079 defined in port.h, in setDefaultOptions() linkOptions is removed
6080 from initialization assignment, since now it is a set,
6081 parseCmdLine uses setParseWithComma for linkOptions, in
6082 linkEdit() linkOptions are accessed with new function indexSet()
6083 which returns the i'th item of a set variable. See SDCCset.c, in
6084 linkEdit() when calling buildCmdLine(), added linkOptions as
6085 last argument. Now users can pass arguments to gplink via the
6086 -Wl option, main() uses pic16glue() to glue up pic16 programs

6098 * src/pic16/glue.c: commented out some error producing lines
6099 * src/pic16/main.c: __config directives are commented out to stop
6100 gpasm complaining and test the linkage with gplink, _linkCmd and
6101 _asmCmd changed to be more gplink and gpasm friendly
6102 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6103 produced an error when parsed, peep rule 12 is added to utilize
6104 movff, but it is commented out since the pCode does not support
6105 yet a command with 2 address arguments

7144 * src/SDCCicode.c: fixed array add
7146 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7147 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7148 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7150 2003-01-04 <johan AT balder>
7152 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7154 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7155 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7157 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7164 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7165 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7167 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7168 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7170 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7172 * in \sdcc\as\mcs51\ changed these files in order to create an
7173 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7174 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7175 following files to include the previous two files: aslink.dsp,
7176 Makefile.aslink, Makefile.bcc, and Makefile.in.
7178 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7179 .adb instead of .cdb
7181 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7183 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7184 value from option --iram-size.
7186 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7188 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7191 2002-09-18 <wiml AT hhhh.org>
7193 * SDCClrange.h: exposed setFromRange() and setToRange()
7194 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7195 packRegsForAccUse() (bug 542397)
7196 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7197 multiple times and emitting the fetch operations more than once
7198 added aopGetUsesAcc() function to allow binary operators to
7199 fetch their operands in the correct order; made genMinus() emit
7200 compact code for X = LITERAL - Y
7202 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7203 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7204 sprintf() in line 1267.
7206 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7207 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7210 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7211 Changes to aslink (All the changes are marked with 'JCF'):
7213 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7216 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7217 area BSEG. Also moves, if possible, the DATA area down into the internal
7218 ram so more space is available.
7220 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7223 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7224 not bytes. Function summary() which creates a memory usage summary
7225 file with extension .mem. Reports of overlaping stack and small stack
7226 size. If the space for the stack is less than 16 bytes aslink trows a
7229 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7230 the 8051. Option 'y' for memory summary output file.
7232 Changes to sdcc (All the changes are marked with 'JCF'):
7234 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7236 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7237 overlaying area for it (uses RegBankUsed[4]).
7239 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7240 bank zero as used by default. By default aslink locates the stack
7241 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7242 the creation of the .mem file. Delegates the allocation of data area
7243 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7244 the begining of the stack area to aslink.
7246 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7247 glue() in SDCCglue.c creates an area for it.
7249 2002-09-03 Borut Razem <borut.razem AT siol.net>
7250 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7251 sdcc/src/pic/glue.c:
7252 introduced atexit() handler for teporay files removal in case of
7253 errors, assertions, ...
7255 2002-08-29 Borut Razem <borut.razem AT siol.net>
7256 * sdcc/support/cpp2/auto-host_vc_in.h:
7257 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7258 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7259 Maybe there is a similar problem with BORLANDC? It should be checked!
7261 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7262 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7263 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7264 was not executed, and the compiler (cl) launched a warning:
7265 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7267 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7268 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7270 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7271 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7273 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7274 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7275 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7276 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7277 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7278 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7279 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7280 - added Release configuration in VS projects
7281 - review of compiler an linker options
7282 - VC .exe files are generated in bin_vc directory, not to interfere
7283 with binaries generated from other projects (cygwin, mingw, bcc ...)
7285 * sdcc/src/yacc.dsp: added
7287 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7288 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7289 and insert the version number definitions from .version
7291 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7293 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7294 added - genarate auto-host.h using auto-host_vc_in.h as template
7297 removed from CVS, generated automatically
7299 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7300 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7302 2002-08-11 Borut Razem <borut.razem AT siol.net>
7303 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7305 2002-08-10 Borut Razem <borut.razem AT siol.net>
7306 * src/SDCCmain.c (main):
7307 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7308 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7309 The consequence was that some temporary files were not removed.
7312 unification of code in functions tempfilename() and tempfile():
7313 function tempnam() is defined in Visual Studio 6.0 and .NET
7315 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7317 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7318 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7319 - removed compiler command line option /WX: Treats all warnings as errors
7320 - update a list of source files, included into the project
7322 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7323 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7324 changed project type to Generic Project so that can be correcly converted to VS.NET project
7326 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7328 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7330 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7332 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7333 added return 0 statements after assert() to make compiler happy
7335 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7336 added newline in the def file to keep MSC compiler satisfied
7338 * sdcc/src/z80/gen.c:
7339 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7340 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7341 - solved MSC error in function aopDump()
7343 * sdcc_vc.h: define PREFIX as "\\sdcc"
7345 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7346 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7348 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7349 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7350 - Rewrote the register banking algorithm.
7351 - Added pCode live-range analysis to registers (for now, only non-used and
7352 singly-used registers optimized away)
7354 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7356 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
7358 2002-05-10 Scott Dattalo <scott AT dattalo.com>

7381 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7383 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7385 2002-03-28 Johan Knol <johan AT balder>
7387 * src/SDCCval.c: fixed bug #532436
7389 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7391 Added "char *Processor" field to the port structure.
7394 Added -p option. Allows port dependent processor to be specified.
7397 Initialized the new field char *Processor field to NULL in all ports
7400 Compiler generated registers for interrupt context saving
7401 were not getting allocated.
7403 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7406 Fixed left shift. Will promote the left side of a left shift
7407 if a) left shifting more than size of operand or b) when assigned
7408 to something size > size of left side
7410 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7412 tons of changes. Register allocation has been
7413 rewritten. Added customization for the various PICs. Flow
7414 analysis is restructured. ...
7420 Added. device.c is a PIC port hack to accomodate variations
7423 2002-03-13 Michael Hope <michaelh AT vroom>
7425 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7427 2002-03-04 johanknol <johanknol AT manik>
7429 * /src/SDCCval.c: fixed
7431 const unsigned char arr[][2] = { { 0, 1 } };
7432 t18.c:1: error: Initializer element is not constant
7434 2002-03-04 bela <bela AT manik>
7436 * /device/include/mcs51reg.h:
7437 ds89c420 register definition update
7439 2002-03-03 <johan AT FRIJA>
7441 * support/Util/SDCCerr.c: did something, but don't no why anymore
7443 * support/regression/tests/bug-524691.c: made it a little less shy
